Error while unref the pipeline

[张若]

Hi!

I have a pipeline:

imxv4l2src->capsfilter->queue1->imxenc(h264)->parse-------\__tsmux___filesink

                                                  appsrc(klv)->queue2------/

When I am going to stop this pipeline, I stop the klv data input first, then set the pipeline to NULL status. For this two steps, there is no problem. However, when I start to unref this pipeline, it shows errors (each time may be different), sometimes are something related to core dump.

I don't know what is the reason. What I thought is the pipeline is already set to NULL, it should be no problem to unref this pipeline.

So I need your help! Thanks in advance!

Mostly, it will show:

GLib (gthread-posix.c): Unexpected error from C library during 'pthread_mutex_lock': Invalid argument.  Aborting.

Aborted (core dumped)

Get a backtrace with gdb (make sure to have debug symbols). This means
something is locking an invalid (probably freed?) mutex somewhere.
